Sulfonylurea herbicide resistance was crossed into a susceptible (S) prickly lettuce biotype and into ‘Bibb’ (B), a domestic lettuce cultivar, and inheritance of the resistance trait was determined. The best fit for Chi Square analysis of the metsulfuron treated F2generations was a 1:2:1 ratio indicating the trait was controlled by a single nuclear gene with incomplete dominance. F3generations also were treated with metsulfuron. The F3seedlings from resistant F2plants were resistant while the F3seedlings from intermediate F2plants segregated.
